Anyllis spinostylus Liang

(Figures 1I–J)

Anyllis spinostylus Liang in Liang et al., 2005: 301–307, figs. 10–16. Holotype male, Australia (Tasmania) (BPBM) [examined].

Description

Length (from apex of vertex to tip of forewings): male (n = 4), 5.8–6.0 mm; female (n = 5), 7.0– 7.2 mm.

General colour ochraceous brown, posterior area of pronotum pale fuscous, scutellum with brown suffusion medially; head beneath ochraceous, antennal sockets and flagellar base pale fuscous, rostrum with apical segment brown; thorax beneath ochraceous with pleurae partly brownish; legs ochraceous, claws dark brown, fore and middle tarsi brown, tips of spines on hind tibiae and tarsi black; forewings (Figure 1I,J) fuscous, marked with some stramineous spots or irregular markings, with three hyaline white areas on costal area, the first basal and very narrow, the second near middle and being very short and small, and the third subapical, large and elongate, nearly triangular; hindwings hyaline, covered with brown hairs, veins brown; abdomen dark brown to fuscous with segmental margins ochraceous.

External structure as in the generic description. Head (Figure 1I) maximum width (including eyes) 3.2–4.0 times as long as median length. Vertex (Figure 1I) with a distinct median carina, median length 0.4–0.5 times as long as length of pronotum medially. Frons (Figure 1J, also see Liang et al. 2005: 304; fig. 11) in the males moderately bulbous, not strongly compressed laterally, median longitudinal carina indistinct. Pronotum (Figure 1I, also see Liang et al. 2005: 304; fig. 10) with median longitudinal carina obsolete on posterior half, median length 0.6–0.7 times as long as maximum width.

Male genitalia with pygofer high, wider ventrally than dorsally, upper posterior end angularly posteriorly produced in lateral view. Anal segments very short and broad, anal style small; basal anal processes robust and straight, with inner edge without fine spines. Subgenital plates very short and small, apically weakly bilobed, outer margin with one very small angular process. Genital styles slender and elongate, angularly expanded laterad medially, apex hook-like in ventral view. Aedeagal shaft distinctly slender and elongate, slightly arched anteriorly in lateral view, anterior– ventral margin with an angular process subapically, upper anterior edge covered with fine spines in lateral view (see Liang et al. 2005: 304; figs 12–16).

Material examined

Holotype male, Australia: Tasmania, Mt Field, Nat. Park, Dobson Lake, 1000 m, 25 December 1960, collected by J.L. Gressitt, deposited in the Bernice P. Bishop Museum, Honolulu, Hawaii, USA (BPBM).

Paratypes. Australia: two males, Lake Fenton, Mt Field National Park, Tasmania, 1000 m, 42 ◦ 40.6 ′ S, 146 ◦ 37.4 ′ E, 6 December 1999 (J. Keble-Williams), beating Nothofagus cunninghamii (ASCU); two females, same data but collected on 25 January 2000 (ASCU); one male, one female, Mt Arthur, Wellington Range, Tasmania, 1080 m, 42 ◦ 53.0 ′ S, 147 ◦ 13.1 ′ E, 10 February 2000, J. Keble-Williams, beating Nothofagus cunninghamii (ASCU); one female, Tasmania, Mt Field National Park, Lake Dobson Road, 710 m, 2 February 1980 (A. Newton and M. Thayer), Eucalyptus, Nothofagus forest, window trap; [green label]. If designated as holotype specimen must be returned to Australia (AMNH); one female, Tasmania, Hartz Mts NP, Hartz Road, 800 m, 8–10 February [19]80 (A. Newton and M. Thayer), Eucalyptus Scrub, moor edge; beating Eucalyptus sp.; [green label]. If designated as holotype specimen must be returned to Australia (AMNH).

Distribution

Australia (Tasmania).

Remarks

This species can be distinguished from another Tasmanian species A. pseudotiegsi sp. nov. by its relatively elongate body and large size (length male 5.8–6.0 mm, female 7.0– 7.2 mm); vertex with a median carina; pronotum with median carina obsolete on posterior half; forewings (Figure 1I,J) marked with more stramineous spots; genital styles more narrow and slender, apex hook-like in ventral view; and aedeagal shaft elongate and slender (see Liang et al. 2005: 304, figs 12–16).
